Research-based review. The score and figures here are compiled from published specs, verified owner reports, and independent third-party testing — not yet from our own instrumented test rides. We'll update this page when our hands-on numbers replace them. How we score
The verdict
The S2 delivers the moped-style look with hardware and a warranty that actually stand behind it — but the app-unlocked speed modes put the legal risk squarely on you.
Who it's for
Nobody buys an S2 by comparing spec sheets — they buy it because they want the scrambler stance, the banana seat, and the fat 20-inch tires. That is a legitimate reason to buy a bike, and this is the version of it we'd point people toward: a brand with real engineering, real support, and a two-year warranty, in a category otherwise dominated by anonymous clones with no parts pipeline. If you want efficient transport, a Class 3 commuter does the same trip faster, lighter, and for a thousand dollars less. The S2 is a style purchase that happens to be competently built.
Ride feel
The 20×5-inch GRZLY tires define the ride. Run at sensible pressure they soak up potholes, curbs, and rough pavement better than the token 60mm fork does, and the low seat height and long wheelbase make the bike feel planted and unhurried. The BR-30 rear hub is punchy off the line — 2,000W peak will spin the rear tire on loose ground — but the delivery is cadence-flavored rather than the proportional feel of a torque sensor, so it arrives in a slug rather than tracking your effort. At 73 lbs, momentum is the dominant sensation: it's stable in a straight line, deliberate in corners, and a genuine handful to pedal unassisted if the battery dies.
Battery & range reality check
960Wh of Samsung 21700 cells is a big pack by any standard, and it needs to be — fat tires, high weight, and throttle use are all range killers. Super73 quotes up to 75 miles; verified owner reports and independent testing land at 30–45 miles in realistic mixed use, and closer to 25 if you ride mostly on the throttle in the higher-speed modes. Charge times are correspondingly long for a bike this size. The upside of the pack's capacity is that even the pessimistic number covers an entire day of city riding, which is what this bike is actually used for.
The legal asterisk you need to understand
The S2 ships configured as a Class 2 e-bike, and Super73's app exposes selectable ride modes including off-road settings that exceed the 20 and 28 mph limits written into most state e-bike statutes. Riding in those modes on a public road or bike path can take the bike outside the legal definition of an electric bicycle in most states — which in practice can mean it's treated as an unregistered motor vehicle, with the licensing, insurance, and liability consequences that follow, particularly after a crash. Super73 is transparent that the fast modes are for private property, and the hardware isn't the problem. The point is that the responsibility for staying legal transfers to the rider every time they open that menu, and a lot of owners don't realize they've accepted it. Check your own state's rules before you unlock anything.
Build quality
The frame, welds, and finish are a clear step above the moped-style clones the S2 inspired, and Tektro 4-piston hydraulic discs are correctly specified for the weight and speed — this is the spec that makes the bike defensible rather than reckless. The 960Wh pack uses named Samsung cells and the warranty is two years, real terms from a company that will still exist to honor them. The weak link is the Shimano Altus 7-speed: a budget drivetrain on a heavy, high-torque bike, and the part most likely to need attention. Parts availability from Super73 itself is good, which matters because much of this bike is brand-specific.
Value
Purely on capability per dollar, $3,495 is a poor deal — a Class 3 commuter at half the price will out-commute it in every measurable way, and even inside the moped-style category there are cheaper bikes with similar numbers. What that comparison misses is that clone brands vanish, take their parts supply with them, and often ship uncertified batteries. Paying the Super73 premium buys a company that answers the phone, a warranty with a legal entity behind it, and the design that everyone else is copying. If the aesthetic is genuinely why you're buying, that's a reasonable use of the money. If it isn't, buy something else.
The verdict
The 8.3 reflects a well-built, well-braked, big-battery bike that scores below its hardware because of value and the legal grey area its own feature set creates. Buy the S2 because you want exactly this bike, keep it in a compliant mode on public roads, and it's a genuinely good purchase. Buy it expecting a practical commuter and you've overpaid for a look you didn't want.
